参照图1及图2，在本具体实施例中，在所述光机镜头122内嵌的侧面上还设置有感应器开关140，感应器开关140用于感应防尘盖组件130的位置。具体地，在本具体实施例中，感应器开关140在所述光机镜头122内嵌的侧面上设置，当防尘盖组件130完全没有遮挡光机镜头122时，所述感应器开关140检测防尘盖组件130的位置产生开关控制信号控制光机120打开；当防尘盖组件130部分遮挡光机镜头122时，所述感应器开关140检测防尘盖组件130的位置产生开关控制信号控制光机120关闭。
上述投影装置100中防尘盖组件130可滑动的设置于滑槽150中内，一方面使得所述防尘盖组件130不易丢失、光机镜头122的防尘操作简单；另一方面，该防尘盖组件130的滑动还可以实现对所述光机120的开与关。上述防尘盖组件130结构简单不易丢失，采用上述防尘盖组件130的投影装置100结构紧凑、外形美观。

在本实用新型提供的具体实施例中，进一步地，上述投影装置100中所述防尘盖组件130包括：滑轨件132及防尘盖134，所述防尘盖134与所述滑轨件132固定连接，所述滑轨件132上设置的滑轨嵌设于所述滑槽150内。
